Preheat oven to 350°F. Spray a bundt pan with nonstick cooking spray. Set aside.
In a small bowl combine your melted butter, olive oil, minced garlic, italian seasoning and salt. Set aside.
Cut biscuits into quarters.
Cut your block of mozzarella cheese into ¼-½ inch cubes.
In the bottom of your greased bundt pan evenly layer half of your biscuit pieces. Make sure that you have a nice even single layer and do not pack the biscuit dough balls tightly because you want some of the cheese and butter to fill in the cracks.
Spoon half of the melted garlic butter mixture evenly over the top of the dough layer.
Evenly distribute half of the mozzarella cheese cubes and finally half of the pepperoni slices.
Repeat steps 5-7 with the remaining half of your ingredients.
Cover your bundt pan with aluminum foil and bake for 30 minutes.
Remove the foil and bake for an additional 30 minutes until golden brown.
Allow your pull-apart pizza bread to cool in the pan for 5 minutes, then carefully flip the whole thing out onto a serving plate. You will want to gently turn bread back over on your serving dish so that the cheesy pepperoni topping is showing.
You can warm your pizza sauce and place it into a small bowl. You can place it in the center, or on the side, of your pull-apart pizza bread for people to dip their pieces into.
